Special-purpose modules with a useful volume of 20 liters and 30 liters are intended for long-term storage and extinguishing of class A, B, C fires and electrical equipment under voltage with gas fire extinguishing agents (GFEA) (the voltage at which it is possible to extinguish without disconnecting the protected equipment must comply with the requirements of the NTD for GFEA).
They are used for fire protection of premises and equipment, in a modular design, for volumetric fire extinguishing. Structurally, the modules are metal vessels in the form of an ellipsoid. In the upper part of the vessels there is a metal fastening.
In the neck of the vessels there is a shut-off and starting device with an electromechanical actuator (hereinafter EMA), a pressure indicator (pressure gauge), a safety membrane and a pressure alarm (hereinafter SDU). The cylinders of the module are painted white.
The modules are not intended for use in hazardous areas.
The modules are manufactured in the climatic version "UHL", placement category 4 according to GOST 15150, for operation at ambient temperatures from -20 °C to plus 50 °C and relative humidity of no more than 80% at a temperature of 15 °C. The delivery set includes:
The special-purpose modules MGP-20 "SMD" and MGP-30 "SMD" use a locking and starting device (LSD) from Rotarex, which has three types of starting:
The manufacturer can make changes to the design of the module while maintaining its basic operating parameters.
